An important goal in environmental research for industrial activity and sites is the investigation and development of effective adsorbents for chemical pollutants that are widespread, inexpensive, unharmful to the environment, and have the required adsorption selectivity. Organoclays are adsorption materials that can be obtained by modifying clays and clay minerals with various organic compounds through intercalation and surface grafting. Organoclays have important practical applications as adsorbents of a wide range of organic pollutants and some inorganic contaminants. The traditional raw materials for the synthesis of organoclays are phyllosilicates with the expanding structural cell of the smectite group, such as montmorillonite. Moreover, other phyllosilicates and inosilicates are used to synthesize organoclay to a limited extent. The purpose of this review was to analyze the possibility of using minerals of other groups with different abilities to expand the structure and structural charge for the adsorption of chemical environmental pollutants. The structural characteristics of various groups of phyllosilicates and chain minerals that affect their ability to modify organic surfactants and the adsorption properties of prepared organoclays were reviewed.

The effect of Cl−,SO42−, CH3COO−, and NO3− anions on the adsorption of copper, lead, and zinc by an ordinary chernozem has been studied. The effect of the anions on the adsorption of Cu2+, Pb2+, Zn2+...

Laboratory data in Cu2+ adsorption by chernozems and parent rocks in Rostov region show that adsorption isotherms can be approximated by the Langmuir equation, whose parameters ( Kl and C∞) were...

Seed priming has emerged as an innovative and economical technique to elevate seed quality, fostering uniform, swift, and robust germination under both stress and non-stress conditions. This study endeavors to scrutinize the effects of organic (silicic acid, SA) and inorganic (humic acid, HA) acids, alongside their synergistic combinations, on seed quality parameters in three distinct lentil (Lens culinaris) genotypes: IPL-316 (tolerant), PSL-9, and PDL-1 (sensitive). Critical parameters assessed encompass germination percentage, root and shoot length, seed vigor indices I and II, and dry weight under meticulously controlled laboratory conditions. The priming agents were standardized across a spectrum of concentrations and durations. Sterilized seeds were immersed in silicic acid (1, 2, 3, 4, and 5 mM), humic acid (100, 200, 300, 400, 600, 800, and 1000 ppm), and their combinations over varying durations (2 to 18 hours), including control and hydropriming treatments. Following treatment, seeds were air-dried and subjected to growth assessments. The findings reveal that priming significantly bolsters early-stage plant growth across all three lentil genotypes, with the combined application of silicic and humic acids yielding remarkable enhancements in all seed quality parameters, intricately influenced by genotype and treatment combination.
